The double-sided adhesive layer is prevented from being affected by dirt, when the double-sided adhesive layer is grabbed by a manipulator, due to the fact that the supporting degrees of the light release film layer, the double-sided adhesive layer and the first heavy release film layer are not enough, the overall supporting degree is increased by adding the second heavy release film layer, and therefore the integrity of the double-sided adhesive layer is protected.

Description

Technical Field

[0001] The utility model relates to the field of adhesives, in particular to a double-sided adhesive structure capable of improving the support degree. Background Art

[0002] In the prior art, the double-sided adhesive of conventional incoming materials is stacked into a layer of light release film, a layer of double-sided adhesive body, and a layer of thicker heavy release film. The sum of the thickness of the semi-finished TP cover, double-sided adhesive body, and heavy release film is 0.2mm. Among them, due to the thick thickness of the heavy release film, it is not conducive to the customer to tear off the heavy release film during installation. However, if the heavy release film is made thin, the double-sided adhesive structure of the incoming materials will not have enough support. When the robot arm grabs the double-sided adhesive, it will cause the double-sided adhesive to collapse and become uneven, resulting in subsequent attachment errors, which is not conducive to attaching the double-sided adhesive during TP assembly. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a double-sided adhesive structure which can improve the support degree.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a double-sided adhesive structure that can improve the support degree and is used to bond the cover plate and the display screen. Figure 1, including: a light release film layer 10, a double-sided adhesive layer 20, a first heavy release film layer 30 and a second heavy release film layer 40. The two opposite sides of the double-sided adhesive layer 20 are sticky, and the double-sided adhesive layer 20 is removably arranged between the light release film layer 10 and the first heavy release film layer 30, and the second heavy release film layer 40 is removably arranged on the side of the first heavy release film layer 30 away from the double-sided adhesive layer 20. The light release film layer 10 and the first heavy release film layer 30 are used to protect the stickiness of the double-sided adhesive layer 20 and prevent the double-sided adhesive layer 20 from being affected by dirt. When the robot hand grabs the double-sided adhesive layer 20, due to the insufficient support of the light release film layer 10, the double-sided adhesive layer 20 and the first heavy release film layer 30, the present application increases the overall support by adding the second heavy release film layer 40, thereby protecting the integrity of the double-sided adhesive layer 20.

[0025] In one embodiment, the first heavy release film layer 30 and the second heavy release film layer 40 are bonded in a tearable manner, and there is weak adhesion between the first heavy release film layer 30 and the second heavy release film layer 40, so that the staff or automated equipment can tear off the second heavy film, thereby ensuring the lightness and thinness of the product.

[0026] It should be noted that after the robot grabs and carries the double-sided adhesive structure that can improve the support to the specified position, the second release film is torn off to ship to the client, thereby reducing the client's workload.

[0027] In one embodiment, the thickness of the first heavy release film layer 30 is less than the thickness of the second heavy release film layer 40. The thickness of the second heavy release film is used to improve the support of the structure as a whole, and then the second heavy release film is made thicker to meet the robot hand to grasp the structure without damaging the double-sided adhesive layer 20, thereby avoiding the double-sided adhesive layer 20 from being scratched by the robot hand, and the thinner first heavy release film layer 30 is easy to tear off, so that the client can tear it off during installation, while ensuring the support and the convenience of assembly of the client. Preferably, the thickness of the first heavy release film layer 30 is 0.075mm, and the thickness of the second heavy release film layer 40 is 0.125mm.

[0028] See also Figure 2In order for the double-sided adhesive layer 20 to better connect two larger parts, the double-sided adhesive layer 20 is provided with openings in the thickness direction to meet the needs of parts with larger adhesion areas and save the material of the double-sided adhesive layer 20. Accordingly, the first heavy release film layer 30 and the second heavy release film layer 40 are both provided with corresponding openings, which further saves the material of the first heavy release film layer 30 and the second heavy release film layer 40. Preferably, the three openings are aligned to ensure the viscosity of the double-sided adhesive layer 20. Among them, the double-sided adhesive layer 20 in the present application can be OCA glue or OCR glue, PET substrate double-sided glue, non-woven fabric substrate double-sided glue, substrate-free double-sided glue, foam double-sided glue or hot melt adhesive film. Preferably, the first heavy release film layer 30, the second heavy release film layer 40 and the light release film layer 10 are all PET material film layers.

[0029] In one embodiment, the double-sided adhesive layer 20 and the first heavy release film layer 30 are provided with corresponding openings, and the second heavy release film 40 is a rectangular parallelepiped, so that when the mounting space is small, the robot can select any gripping point on the double-sided adhesive structure for attachment.

[0030] In addition, the light release film layer 10 is a rectangular parallelepiped, so that the robot can grab the double-sided adhesive structure with improved support of the present application and protect the integrity of the double-sided adhesive structure with improved support to a certain extent.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
